由于PC可以给出的蜂鸣代码数量，超级用户有很多关于蜂鸣代码的问题！我希望这篇文章将有助于提供有关所有（我敢说所有？）哔声代码的社区答案，以及我虚构的问题。
当我尝试打开我的电脑时，我听到了一些哔哔声。这不是来自 HDD 或风扇的蜂鸣声，而是来自主板的蜂鸣声。不管哔哔声有多少，哔哔声是什么意思？
蜂鸣声通常称为蜂鸣代码。它们提供了一个指示，通常是关于某些硬件的状态。
哔声代码是计算机发出的音频信号，用于宣布计算机在首次开机时执行的简短诊断测试序列的结果（称为开机自检或 POST ）。POST 是包含在计算机的基本输入/输出操作系统 (BIOS) 中的一个小程序，它会检查以确保存在必要的硬件并且可以访问所需的内存。如果一切测试正确，计算机通常会发出一声哔哔声并继续启动过程。如果出现问题，计算机将在显示器屏幕上显示错误消息，并通过一系列音调、次数和持续时间不同的蜂鸣声以可听见的方式宣布错误（这在显示器或图形组件存在错误时特别有用） .
哔声代码没有官方标准；音频模式因计算机 BIOS 程序的制造商而异。如果在启动时发出错误消息，用户必须首先确定计算机正在运行哪种类型的 BIOS（Phoenix 或 AMI 是最流行的），并使用该信息查找正在发送的特定哔声代码序列。BIOS 信息和哔声代码解释可以在计算机随附的手册和制造商的网站上找到。
因此，要理解它，您需要做的第一件事就是找出您拥有的 BIOS（这可以通过阅读手册来实现。如果您没有，制造商通常会在他们的网站上保留一份电子副本。另外请参阅如何找出我的计算机中的主板？
现在，哔声代码：
